Abstract: At the present stage of technology development, continuous medium viscosity measurements are relevant in various fields of human life: oil and gas industry, aviation, food industry, in the synthesis of man-made and synthetic polymers, healthcare industry etc. In order to improve the technological process, one of the priority tasks is the development of new research methods and viscosity calculations. The article presents the descrip-tion of a part of “Rheotest – 2” rotational viscometer that is used for determining the viscosity of a small volume liquid. To determine the test material viscosity, volume from 0.1 to 0.3 ml is required. The part was de-veloped at the Department of Applied Mechanics of the FSBEI HE “Kemerovo Institute of the Food Science and Technology (University)”. The part consists of a nozzle and a base coat. The difference from the “Rheotest-2” rotary viscometer is that the bottom of the body structure has a recess of 10 mm in diameter in the center for investigated material, the sealed cover is provided with an elastic sealing along the perimeter and latch mechanisms. The approbation of the part was carried out using the substance with known viscosity. Glycerol was used, 5 measurements were made, in all experiments the viscosity corresponded to the declared parameters.

Key words: viscosity viscometer rotary "Rheotest - 2" small volume
